Application tiled Detolier 17, 1888. Serial No. 288,358. (No model.)

To all whom it may concern:

Be it known that I, PETER GENDRON, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improve ments in llachin'es for Trimming l/Vire Spokes, of which the following is a speeiiication, refer ence being had therein to the accompanying' drawings.

This .invention relates to new and useful improvements in a machine for trimming wire'spokes, and the invention is especially designed to be used in the manufacture of such iron wheels in which the spokes are formed of wire, and wherein the spokes have to be cut off at the ends at equal length after they are secured to the hub and before the rim of the wheel is secured thereto.

My invention consists in the peculiar construction and arrangement of the cutting devices for cutting off the ends of the spokes, and of a wheel-support adapted to permit of adjusting the wheel in proper relation to the cutting device, and of revolviilg the wheel so as to present the spokes successively to the cutting oi'i devices, all as more fully hereinafter described, and shown in the accompanying (.lrawings, in which-- Figure l is a plan ol my machine; Fig. 2, a vertical central longitudinal section; Fig. 3, a cross-section on Aline .r .fr of Fig. l; and Fig. ll Vis a detached perspective view of the cutting-olif devices and the rotary wl1eelsupport.

A is the bed of the machine, provided with suitable legs and supporting at one end in suitable bearings, l'l, the horizontal drive-shal`t (l, which is provided at its outer end with the drive-pulley l) and at its inner end with a rotary cutter, E. This rotary cutter is provided with a series of circumferential cuttingteeth, F, as shown in Fig. il, o being the cutting-edge of each tootlnand this cutting-edge is concave to conform to the cross-section of a wire spoke. ln close proximity tothe inner vertical face of this rotary cutter is secured, upon the bed of the machine, the stationary cutting-bleak (l, the edge I) ol' which forms the stationamv eutting-edge, which operates in conjunction with the mating-edges u of the rotary cutter to trim the spokes. This cutting-block is detachably secured in a suitable manner to the knife-holder H, secured upon the bed of the machine in front of the rotary cutter-head, as shown in Fig. 4.

I, Fig. l, is a longitudinal slot through the center of the bed in the vertical axial plane of the cutter-head, and in this slot is slidingly secured the wheelsupport, which consists of the sliding` bearing J, adapted to be adjusted back and forth within the slot and secured therein by means of a suitable clamp-bolt, K. In this bearing is journaled a vertical stopshaft, L, split through its center and tapered at its end c. Upon this stop-shaft is secured the dog M, which rests on top of the bearing J, and to the lower end of the stop-shaft is secured the cord-pulley N, and to an arm, O, Figs. l and 2, projecting laterally, is secured the cord-pulley P. Upon the shaft C of the rotary cutter-head is formed a suitable cordpullcy, Q, and vertically below this, underneath the bed, are secured the cord-pulleys R and S, and on the opposite end of the bed is secured to a slidingly-adjustable bearing, T, the cord-pulley U, all so arranged that by means of the endless cord V, passing' over these various pulleys, as shown, motion transmitted from the cord-pulley Q on the shaft C to the revolving shaft L o'l' the wheel-support. By means of the combination of the pulleys N and P the wheel-support may be adjusted back and forth in the slot without altering the tension of the drive-cord.

The pulleys Rand S, as will bc well understood, are guide-pulleys to change the direc tion of the cord from vertical to horizontal, while the cord-pulley U at the end of the bed permits the tightening of the cord by means of the adjusting-screw W through the end ot' the bed, which screw engages into the sliding bearing T, which carries the cord-pulley. A similar adj listing-screw, X, passing longitudinally underneath the bed, engages with the sliding bearing of the wheel-support, and `thereby forms the means of adjusting the wheel-support at any desired distance from the rotary Vcutter-head, said dist-ance being marked by a scale, Y, on the edges of the slot I, and the indicator-hand Z on the sliding bearing permits of indicating the distance accurately,

d is a guide-rail. secured to the bed of the machine in the vertical. plane of the cu'tterhead, and this is provided at its free end with IOO head, and another guide-rail, j', is secured an incline, e, to `guide the spokes downwardly into the cutting-teeth of the rotary cutterupon the bed to lead the spokes upwardly into the teeth of the rotary cutter-head by means of its incline g. The guide-rail d is preferably curved above the cutter-head to form a guard therefor, as shown in Fig. 3.

In practice, the parts being arranged and constructed substantially as shown and described, they are intended to operate as follows: The wheel, the spokes of which are intended to be operated upon by the machine, :is engaged with its hub upon the shaft L oli' the wheel-support. This shaft is made to [it the hub snugly, and by having it split, as de scribed, the hub can be readily engaged with it without having any lost motion thereon. The dog M has its outer ends curved upwardly to engage between the spokes of the wheel, and thereby revolves the wheel with the shaft L upon motion being given to the machine. It will readily be seen that the motion is communicated through the cord V from the shaft Cto the shaft L of the wheelsupport, and the wheel being' carried thereby will be revolved in the direction of the arrow shown in Fig. l., while the cutter revolves in the direction shown by the arrow in Fig. Thus the ends of the spokes will be successively carried into the teeth of the rotary cutter-head which trims or cuts off the ends at the required length and at uniform length for every spoke. If any of the spokes should be ont of line, the inclined guide-rails f and d will carry the spoke to the proper place for cutting-that is, resting with its end on the stationary knife-block G. It is obvious that by the manipulation of the set-screw X the wheel-support can be adjusted accurately to cut the spokes off at the desired length, and i by constructing the machine of suitable size sufficient adjustability nis provided to use the machines for wheels of all sizes.

What I claim as my invention isvl. In a machine for the purpose described, the combination of a rotary cutter-head provided with peripheral eutting-teeth, with a stationary knife-block operated in connection therewith, an adjustable wheel-support, and a rotary shaft positively and automatically operated from the mechanism actuating the said cutter-head, substantially as described.

In a machine for the purpose described, the combination of the rotary cutter-head, the stationary knife-block operating in connection therewith, and an adjustable wheel-support provided with a rotary shaft and dog to rotate the wheel. l
